Final answer:
At an intersection without signs or lights, be prepared to yield to other vehicles and pedestrians, ensuring safety and order. Traffic signals are crucial for pedestrian safety, especially for students near school campuses, as they help regulate vehicle speeds and organize safe crossing times.
Step-by-step explanation:
When two roads intersect without signs or lights as guidance, be prepared to yield to vehicles that have arrived before you or to those coming from your right. This approach ensures safety and order on the roads in the absence of traffic signals, which typically manage the flow of traffic and pedestrian crossings. Uncontrolled intersections require drivers to be extra cautious and observant. For pedestrians, particularly students commuting to or from campus, crossing such intersections can be risky. The absence of a traffic signal means they have to be vigilant and cross only when it is safe to do so, often having to navigate through moving vehicles that may fail to slow down, despite the speed limit.
Highlighted in discussions about road safety is the impact a traffic signal can have on reducing vehicle speeds and organizing crosswalks for safer pedestrian transit. A signal can significantly lower the risk of accidents, which can unfortunately include serious injuries or loss of life. It provides structured intervals, allowing pedestrians to cross at designated times without the danger of dodging traffic. The need for traffic signals at busy intersections near school campuses is underscored by the responsibility of ensuring the safety of young commuters.
